, LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent ,No. 308,318, datedNovember 18, 1884.

Application filed December 6. 1883.

To all whom it may concern:

Be it known that I, JAMES MAGEE, a citizen of the United States,residing at \Vesterly, in the county of Washington and State of RhodeIsland, have invented a new and useful Improvementin Loom-Shuttles, ofwhich the following is a full, clear, and exact description,referencebeing had to the accompanying drawings, forming a part of thisspecification.

The object of my invention is to regulate the tension of the thread asit passes off of the bobbin; and to this end my invention consists inthe peculiar and novel construction and arrangement of parts, ashereinafter described and claimed.

In order that my invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, in which-- pFigure 1 is a plan View of the shuttle with its bobbin andtension-regulating roller in operative position. Fig. 2 is a view,partly in side elevation and partly in vertical section, of one end ofthe shuttle, showing the tensionregulating device in operative position.

In the said drawings, A designates the shuttle-body, and a its eye.

13 designates the bobbin, and Z designates a strand of thread passingoff fromthe bobbin and out through the eye a of the shuttle-body.

As my present invention does not relate particularly to the mounting ofthe bobbin in the shuttle body, it will suffice to say that the bobbinis mounted on a spindle which passes longitudinally into the body of thebobbin and is hinged at one extremity in the end of the shuttle-body.The hinge is provided with a spring, which serves not only to hold thespindle in operative position, but also to hold the bobbin from movingon the spindle. When the bobbin is depleted, the spindle is raised atits free end and the bobbin is re- (No model.)

moved. A full bobbin having been placed on the spindle, the latter isdepressed and is held down by its hingespring, and the outer end 5 ofsaid spring also presses from beneath into the notch b of the bobbin,holding the latter from turning or sliding on the spindle. I do notconfine myself exclusively to this arrangement of the bobbin, but preferit to others which may be used.

0 designates a cylindrical roller, which extends transversely of theshuttle, and the ends of which are confined between two inverted-U-shaped straps, c, which are secured to the sides of the shuttle-body.This roller 0 rests upon an inclined plate or shelf, D, the pitch ofwhich is downward toward the free end X of the bobbin. The thread,passing from the bobbin out through the eye, is carried between theroller G and the platform D. The forward edge ofthe plateD is held byscrews, as shown, which pass down into the portion 1) of theshuttlebody. The lower ends of the straps 0 pass through the edges ofthe plate D, and are bent at right angles beneath said plate. Thus itwill be seen that as the thread is fed off of the bobbin it will be keptunder a constant tension by the roller 0, and all slack and knottingwill be avoided.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination, with the shuttle-body having theportion 1), of the shelf D, secured to said body and inclined toward thefree end of the bobbin, the straps c, secured in the sides of the bodyand bent beneath the shelf D, and the cylindrical roller resting uponthe shelf and confined in its movements by the straps, all substantiallyas described.

JAMES MAGEE.
